The Cortex-M7 has 3 options for its FPU: none, FPv5-SP-D16 and FPv5-DP-D16. FPv5 has the same instructions as FP-ARMv8, so it can be modelled using the same target feature, and all double-precision operations are already disabled by the fp-only-sp target features. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218747 91177308-0d34-0410-b5e6-96231b3b80d8
